E2 Version 1.3.2 release includes:

• A bug fix to the Riparian Particulate Model plugin
• A change in the time bomb
• Changes to the persistence mechanise to improve the speed of saving and loading.

E2 1.3.1b Release Notes (September 2006)

Fixed: The data grid on the Map tool was not showing the values corresponding to the correct sub-catchment. Only the grid was erroneous; the data shown on the map itself was correct and exported correctly as a shapefile

Fixed: The spatial data needed to paramaterise the Riparian Particulate Model was not saved to disk and the model could not be re-parameterised as easily after reloading a project file.

Added: Optional plugin rainfall-runoff models SURM (Simple Urban Runoff Model) and SMAR

E2 1.3.0 Release Notes (August 2006)

Improved: Additional raster layers or images can be dropped as a background onto the scenario forms.

Improved: Results from the Map tool can be exported as a shape file, and displayed in a grid format

Improved: Saving projects is 10-30% faster due to performance improvements.

Improved: Several more minor usability and "look and feel" issues have been dealt with, e.g. some nodes appearing white on a white background.

Improved: Time series and other data types can be dragged from graphs, and copied onto the main form by holding the "Ctrl" key. The copied time series is then not affected by rerunning the scenario, and can be used for time series comparisons.

Added: The Riparian Particulate Model is now available as an optional plug-in

Added: Node, link and sub-catchment names can now be edited via a link under the Scenario menu

Added: Spatial data can be exported from the network definition step.

Added: The "observed flow" node model was lacking an appropriate form to configure it. Although it was not intended to be used directly, it can be. A form to input a time series has been added.

Fixed: In some circumstances the use of the Laurenson routing scheme could lead to time series of constituents in nodes and links to become what appeared as "empty" because they were not showing on a time series graph anymore.

Fixed: Some EMSS-related optional configuration tools were missing as plug-ins from the version 1.2.2

Fixed: E2 now releases and frees-up memory correctly. Previously, memory was not always reclaimed when it should be (e.g. when closing a scenario), and could lead to "out of memory" exceptions. This is arguably the most serious usability issue dealt with in this release.

New beta expiry date: 1 March, 2007

Known Issues

It is known that the Sacramento model is needed by some users. Due to some purely technical difficulties related to Sacramento being written in Fortran, it cannot be included as a plug-in in the main installer. It may however be provided as an optional download on this page if other delivery mechanisms can bypass these technical issues.

Release Notes - E2 - Version 1.2.2 beta

This minor release mainly fixes two issues in the previous release 1.2.1b: one related to having more than one additional node per sub-catchment in the catchment definition based on a DEM, and a issue for scenarios derived by copying an existing scenario that includes water ordering node models. When loading existing scenarios, a check has been added that will provide the details of the second issue to the user with action to take to resolve the issue.

Bug Fixes

• [ETWO-335] - "Node Models" deep copy issue: issue when node models reference reservoirs if project has several scenarios
• [ETWO-349] - Additional Nodes in stream define not working sensibly on the Yarra catchment
• [ETWO-350] - Map analysis tool shows NullValues on catchments for which there should be a value
• [ETWO-142] - Network layer causes crash when viewcontrol reduced to line or zero-area zone
• [ETWO-338] - Possible run-time exception with multiple scenarios projects but with different constituents in each scenario.
• [ETWO-347] - Exception thrown on selecting a sub-catchment on the main scenario form, Date: 22/11/2005 5:40:17 PM
• [ETWO-107] - Applying a parameter set: "Apply to all" was enabled yet none is selected

New Feature

• [ETWO-33] - Add data export formats (particularly enable Shapefile export of maps)  from network definition
• [ETWO-278] - Accessing the generated stream map and saving it.
• [ETWO-284] - Indicate (in Project Manager or on main form title/caption) which scenario is active
• [ETWO-327] - Allow for users to specify the units of their constituent (hidden feature).
• [ETWO-328] - Automated tests for backward compatibility of relational data persistence

Improvement

• Graphs now have a background grid by default
• Minor changes to the Run Scenario form for consistency with calibration mode "run scenario" panel
• [ETWO-337] - Model Explorer needs to show in the form title which scenario is explored

Version 1.2.1b is mostly a fix release solving issues found in release 1.2.0b. The main change users may first notice is that some models and options for configuring the system are now optional and available as plug-ins. The main reason for that is that some options for assigning rainfall and PET inputs to the models were slowing down drastically the display of the input assignment step in some circumstances. You may thus need to load some additional plugins (in a folder "Plugins" under the E2 program folder) in order to reload your previous projects.

The main issues solved by this version are:

• The named parameter sets were not correctly re-read from the project file and were reset to zero. Note however that the parameters in the model themselves were correctly retrieved in version 1.2.0; only the named parameter sets were affected
• The list of models available now reflects the content of the loaded plug-ins
• The options available in the wizard that were computation-intensive (e.g. SILO input assignment) are now optional and located in a seperate plug-in
• All unhandled "exceptions" will now generate a bug report that can be submitted online
• The model "Loss at a node" could be saved but not retrieved from the saved project file
• The Music K-C* has two sets of k and C* parameters: one for quickflow and one for slowflow
• Missing Zoom/Pan on the manual network definer
• Grids to access model parameters were not reflecting on integer parameters (e.g. lag)
• EMSS routing is now an optional flow routing model available as a plug-in

Version 1.2.0 has expanded considerably upon release 1.0.0, with the following features:

• Improved project saving and loading
• Expanded options for common processes, such as assignment of FU areas
• Increased number of component models
• Addition of a range of pre-processing tools
• Increased data analysis and manipulation capabilities, including terrain analysis tools
• Specific options for integration of compatible Catchment Modelling Toolkits products, such as the Irrigation drainage and 2CSalt models
• Development of a plug-in capability, to support advanced integration of compatible components from within a range of Catchment Modelling Toolkit products.
